Using the periodic table as a model, students are asked to complete a graphic organizer that could be used to predict the charges of stable ions formed from atoms in a group on the periodic table.
Atoms are __________ because they have the same number of protons and electrons. However, based on valence electrons, some atoms will easily gain or lose electrons to other atoms in order to achieve noble gas electronic structure. __________are atoms that have gained or lost electrons.  Atoms that have __________ electrons have a positive charge and are called __________.  Atoms that have __________ electrons have a negative charge and are called __________.
